Preserved Fulltext
To address this issue, we propose a signal denoising method based on ensemble empirical mode decomposition (EEMD) and MSPCA. ...
Synthetic tests demonstrate that the EEMD-MSPCA-based method can provide good signal denoising results and is superior to the low-pass filter, wavelet reconstruction, EEMD reconstruction, Hankel–SVD, EEMD-Hankel–SVD ...
